Add background note in elf_tlsgd.c.
Also some code cleanup, and a fix for an (extant unrelated) missing
<pthread_np.h> include that should hopefully resolve a failure in the
FreeBSD CI build, since it is best to make sure that this MR actually
builds on FreeBSD systems other than mine.
Some unexpected metric changes on FreeBSD (perhaps because CI had been
failing for a while???):
